Why is my power supply not working?

Insufficient Power Supply Cause: The power source does not provide enough current to operate the circuit. Solution: Verify that the power supply meets the current requirements of the circuit. Ensure the voltage output is stable and matches the circuit specifications. 4. Incorrect Connections

What determines the maximum current a battery can supply?

It only determines how long the battery can supply a current for (that is, how much energy is can output over a period of time). The max current is determined by it's internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances.

How does a regulator know if a battery is undercharged?

The regulator only knows if the voltage is dropping. If the battery is undercharged (lower open circuit voltage) it draws more current because it is providing less resistance. This causes the voltage to fall which causes the regulator to increase the current output of the alternator.

Why does my power supply have zero amps?

Another reason for zero amps could be incorrect measurement techniques, such as connecting a multimeter in parallel and blowing its fuse. Verify correct connections, measure resistance, test components, and ensure power supply compatibility to solve this problem. Several factors can cause voltage but no current. Possible causes are: 1. Open Circuit

How do I know if my battery is bad?

Call the maker. Amp draws that are stated are a guarantee but batteries don't have predictable maximums. Any battery that gets shorted, for example, will use up an unpredictable amount of current until it dies. And before that, you have no idea what kind of damage occurs inside. Call the maker.

What causes voltage but no current?

Several factors can cause voltage but no current. Possible causes are: 1. Open Circuit Cause: A break or disconnection in the circuit. Solution: Check for loose or disconnected wires, damaged components, or switches that are not closed. Repair or replace any faulty elements to complete the circuit. 2. Faulty Components
